Socialism is based on public ownership of means of production. In order to shift to socialism in foreseeable future and in the past, it requires forceful removal of private property and converting it into public, since I can not imagine that all people would do this voluntarily (and they did not do that voluntarily historically). So, yes, you require forceful state, a dictatorship. Soviets openly called that “dictatorship of the working class” when they were nationalizing means of production. That included by the way farmers who used seasonally hired labour. They fought to destroy those farms and farmers were treated as enemy to socialism. Ukrainian Holodomor that killed millions of people is a good example of such fight.

So, before blank-calling other people self-centered and selfish, maybe you should learn a bit more about socialism and its history?
